Gmoccapy - A new screen for linuxcnc

Thank you so much for your time and effort. Have you created all the links that I needed, like I have spindle PWM control, ATC etc. So all that should work now, you have created the spindle feedback links and all that too? And also my ATC comp will work and the links to gmoccapy have been created like tool number showing dro and stuff?

OK, so I should not copy these files to my existing turn profile folder? If yes, then how can I start this profile because the only way to start linuxcnc I know is from the desktop which was created through step config but obviously that is going to look for files in my existing folder. If I want to start this profile, what is the process? Run terminal? And what will be the command?

How about if I delete everything from my config/turn profile folder and copy these news files in there which you cleaned up, will that work?

And thank you so so much for cleaning up my files, obviously there would be too much junk as I am just a kid learning linuxcnc

Await your reply and sorry about bothering you too much, excuse my ignorance, but I really like Gmoccapy and I wanted to run it.

And there was another file emcochanger.comp which I installed earlier but I no longer load that file or use that comp because I created new comp Oracchanger.comp which I load in hal and run. Can I also delete the other file emcochanger as I do not load it with hal?

Make a new folder in ~/linuxcnc/configs (~ being your home folder)
place all ziped files in there.

Yes you can delete emcochanger.comp.

Now go to the start menu /applications / CNC / linuxcnc
A config picker will apear, select there the new config and start it.

All should work except the tool offsets will not be shown.
To add that feature, place the following lines at the end of your postgui.hal file

Thank you so very much for all your help. I will try tonight and will let you know if there is any problem. Excited to see gmoccapy running for the first time, cant wait.

I do not have any offsets set anyway and I do not use them either but thank you so very much, in case I do need in the future, I will be able to add as per your advice.

Again, cannot thank you enough Norbert and thank you for giving lovely GUI.

Hello Norbert

I ran my gmoccapy profile which you provided the other day. It ran perfect without any error. Very nice GUI.

However I have a problem, spindle rpm are not stable and when I cut the threads today, the motion was very jerky as if the AXIS was responding to the ever changing speed of my spindle. Like it was stopping or slowing down and accelerating so threads were all over the place.

I check my INDEX and PHASE A signals with halscope and signals were very inconsistent, at lower rpm like 50 rpm, PHASE A is in good shape but above that either it misses the pulses or keep it ON for 5 or 6 pulses together. INDEX signal, there are some weird spikes.

I cut the threads and checked the signals previous week, it was very nice and clean and the threads were very smooth and proper.

Is there any settings I can play with in linuxcnc. I have 1 pulse per revolution for INDEX and 100 on PHASE A. Do you think this is because of noise on the lines? My encoder plate with 100 holes and one index notch is very precise made by a professional lathe company, EMCO. The sensors are in good shape and proper in line with the plate. I do not know where is this noise coming from when it was not there a week ago. Do you have any suggestions how can I clean the signals back to my parallel port. Is there any sort of debounce setting I can play with or even hardware, any suggestions to add any circuit to my line? Like resistor or capacitor to clean the line?

I have optical sensors on the encoders and the signals were very stable and clean before. Any suggestions please. Any hardware fix?

Thank you.

Glad gmoccapy is running.

For the spindle stuff, please open a new thread, as this has nothing to do with gmoccapy.
I am not the hardware expert, and I did never use a encoder through the parport, sorry.

Norbert
